CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No 459,041, dated September8, 1891.

Application iiled April 16,1891. Serial No. 339,135. (No model.)

T0 @ZZ whom it may concern:

Be it known that l, GEORGE HARDY, of Lawrence, county of Essex, State ofMassachusetts, have invented an Improvement in Gar-Couplings, of whichthe following description, in connection with the accompanying drawings,is a specification, like letters on the drawings representing likeparts.

This invention has for its object to improve the const-ruction ofcar-couplings such as shown and described in United States Patent No.411,410, dated November 251800.

In accordance with this invention the oscillating draw-bar having alaterally-projecting draw-head with a beveled inclined abutting' face isprovided on the opposite side of said draw-head with a beveled engagingface. A suitable hook is also arranged on the drawbar,which may beemployed to receive a link when, for instance, a car provided with acoupling of the construction herein represented nieets a car providedwith the ordinary link-and-pin coupling. Back of and adjacent to saidhook a suitable projection or shoulder is formed to prevent the linkfrom being pushed rearwardly.

A suitable locking device is provided for locking the draw-barin fixedposition against oscillating motion when said draw-bar is pulled outagainst its cushioning-spring. A sector is secured to or formed on thedrawbar, which has connected to it a chain by which the said bar may beoscillated, and said sector is locatedbetween suitable guide-plates forprotection.

Figure 1 is an under side view of the carcoupling embodying thisinvention applied to two car-frames and properly coupled; Fig. 2, anenlarged sectional View of one ot the carframes, the draw-bar beingshown in elevation; Fig. 3, an end View ot' one of the carframcs andportions of the coupling shown in Fig. 1, and Fig. al a transversesectional detail of the draw-head.

The car-frame may be of any usual or suit able construction, and isprovided, as herein shown, with a bniter-plate a, having an annularmetallic bearing portion d fitting the block a2.

The draw-bar l) has itsbearin gs in said butfer-plate ct at its forwardend and at its rear end passes through a box or case which contains aspiral spring c', surrounding said d raw-bar and acting as acushioning-spring for said draw-bar. The draw-bar Z) has 011 it aprojection b', entering a recessed portion in the bearings of thebutter-plate a, said recess comprising an arc ot' about ninetydegrees toenable the draw-bar to be oscillated such a distance.

A collar d is splined or otherwise mounted on the draw-bar l), to whichis attached a sector d, a spiral spring d2 encircling said collar andattached at one end to a fixed point, as at 2, and the other end to thecollar, said spring operating as a restoring-spring for the draw-bar torestore it to its normal position after it has been moved by the sector.

A chain or cord is attached to the sector, which has attached to it twochains passing over suitable pulleys, which are employed as a means foroscillating the draw-bar, one of the said chains being accessible fromthe top of the car and the other from the side, as shown.

The draw-bar has at its front end a drawhead b2, projecting laterallyand pointing downwardly, the abutting side or face of which is inclinedand also beveled, as represented in Fig. 1, and its opposite side beingat substantially right angles wit-h relation to the draw-bar, butbeveled transversely, as also represented in Fig. 1, so that such faces,which serve as the engaging-faces for the drawheads, will enable thecars to turn a curve and still maintain the same angle of incidence.Each draw-head is also provided with a hook b3, which may receive a linkof any well-known construction, and just back ot` and adjacent to saidhook a suitable proj ection or shoulder b* is formed to prevent the linkfrom being' pushed rearwardly. The draw-bar has also keyed on it, asherein represented, at its rear end ablock or collar having a projectione, which enters a slot or passage c, formed in av plate c2, secured tothe frame or forming part of the bon or case containing' thecushioning-spring c.. lVhen the draw-bar is drawn out by the pullingapart of two cars, the projection e, entering said slot e', will lockthe draw-bar against oscillating motion.

A suitable guide a" is formed integral with or attached to thebuffer-plate a, and another IOO guide d5 is located adjacent said guidea4 and presents a guide-passage for the sector d.

When the cars come together to be automatically coupled, the beveledinclined faces abutting cause each draw-bar to turn sufliciently toenable said draw-heads to pass each other immediately after theactuating-sprin gs cl2 restore them to their normal position, engagingone another, as represented in Fig. l. When it is desired to uncouplethe cars, the sector d is moved by the chain and one of said draw-headsturned With relation to the other.

I do not desire to limit myself to the particular form of locking deviceherein shown, as it is obvious that any'other form of Ylocking devicemay be employed Without departing from my invention. j

When a car provided with the coupling herein shown and described meets acar having the ordinary link-and-pin coupling, the link Will be made toengage the hook h3.

I claim 1. In a car-coupling, a recessed buffer, the oscillatingdraw-bar provided with a downwardly-projecting draw-head having abeveled inclined abutting face, and a projection on said draw-bar toenter the recess in the buffer-plate, substantially as described.

2. In a car-coupling, the spring-controlled oscillating draw-barprovided with a downwardly-projecting draw-head having a beveled andinclined abutting face and a transversely-beveled engaging-face at rightangles to the axis of the draw-bar and opposite said abutting face,substantially as described.

3. In a car-coupling,an oscillating springactuated draw-bar providedwith a beveled face and a hook adapted to receive a link, and

a retaining shoulder or projection for said hook back of but adjacent tosaid hook, as and for the purpose set forth.

4. In a car-coupling, an oscillating and longitudinally-movabledraw-bar, combined With a locking device actuated by longitudinalmovement of and for locking said draw-bar against oscillating motionwhen it has been moved outwardly, substantially as described.

5. In a car-coupling, an oscillating drawbar having a spline thereon, acollar d on said draw-bar provided with a splineway to receive saidspline, whereby rotation of the collar rotates the draw-bar, the latterbeing freely movable longitudinally in said collar, the sector d yspring d2, encircling the collar and retaining said draw-bar in normalposition, and a chain or equivalent for moving it by said sector,substantially as described.

6. In a car-coupling, the oscillating drawbar and sector thereon,combined with guideplates a4 a5, between which said sector is placed,substantially as described.

7. In a car-coupling, the oscillating drawbar having a projection `b' onit, combined with the buffer-plate a, having the metallic bearing aformed integral with the bufferplate, substantially as described.

S. In a car-coupling, the oscillating and longitudinally-movabledraw-bar having the projection e on it, combined With the plate e2,having a slot e', substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

GEORGE HARDY.
